Quick question, has anyone managed to achieve a scenario with facet filters where they can get it to treat selections of facets with the operator 'and' but also 'or' too. We would preferably like to have the results at the top of the list using the 'and' operator but once these results end, it would use 'or'.

I'm not sure this is possible to do with the native instantsearch widgets. But you might be able to do this with a custom widget...
